In general, when you plan to prepare NPK fertilizer, there are two methods that are popular with NPK fertilizer manufactures. They are NPK fertilizer granulation line and NPK fertilizer blending system. The former can help you turn powder chemical fertilizer into NPK fertilizer pellets. While the latter can process granular chemical fertilizer into NPK fertilizer you need. You can choose one from them according to your material, budget, factory area, etc. If you have any requirements, you can contact us immediately for solutions. We can provide you with customized NPK fertilizer plant design.

How to choose materials for your NPK fertilizer manufacturing?

For NPK fertilizer preparation, the first step is material selection. For this, there are two items you need to focus on when choosing the materials for NPK fertilizer production.

NPK fertilizer making materials types

NPK fertilizer making, as the name suggests, is prepare fertilizer which contains rich elements of nitrogen, phosphorous and potassium. Then what material can supply nitrogen, phosphorous and potassium elements in your fertilizer making process?

If you want to make NPK fertilizer with rich nitrogen elements. You can use urea, ammonium chloride, ammonium sulfate, ammonium nitrate, calcium nitrate, etc as materials.

When you want to increase the phosphorous content of your NPK fertilizer. Monoammonium phosphate (MAP), diammonium phosphate (DAP), triple superphosphate (TSP) and superphosphate (SSP) are excellent options for you.

Then for potassium nutrient supply, you can prepare NPK fertilizer with chloride (MOP), potassium sulfate (SOP), potassium carbonate and plant ash, etc.

NPK fertilizer production materials

NPK fertilizer preparation materials shapes

Provided you plan to produce NPK fertilizer with NPK fertilizer granulation line, we recommend you choose powder chemical materials. But if you prefer NPK fertilizer blending system, you should buy granular N, P, K materials.

How to make powder chemical materials into NPK fertilizer granules?

If you plan to prepare NPK fertilizer which can help you make more profits, our NPK fertilizer granulation line is an ideal choice for you. It can help you make powder chemical materials into NPK fertilizer granules quickly and easily. Then what is the design of NPK fertilizer granulation line?

Chemical material crusher

The finer the chemical powder, the better the final NPK fertilizer pellets quality. Therefore, a suitable crusher is necessary for your NPK compound fertilizer making. Here, vertical type crusher and cage crusher are both excellent choices for you.

Dynamic batching machine for NPK fertilizer preparing

Dynamic batching machine

You may want to produce 15-15-15 NPK fertilizer or 20-10-10 NPK fertilizer, how to make the proportion of N, P, K is in line with your formula? Our dynamic batching machine equips each material hopper with an electronic belt scale. In this way, it can feed materials precisely to make required NPK fertilizer.

Compound fertilizer granulator

Granulation equipment plays an important role in the preparation of NPK pellet fertilizer. It is used in making powder chemical materials into granules. For this, you can purchase disc granulator, rotary drum pelletizer and double roller granulation machine.

Rotary granules screener

After granulation, in order to ensure the quality of NPK fertilizer pellets you produce, it is advisable to sieve them with rotary screener. Which can separator required size NPK granules from others. Then you can transport qualified granular NPK fertilizer to the next process.

Chain crusher

How to dispose of the unqualified NPK fertilizer granules? Or discard them? What a waste! At that time, you can use chain crusher to grind them into fine powder again and return then to reprocess.

Dryer and cooler for better fertilizer manufacturing

Dryer and cooler

If you use double roller granulator to prepare NPK fertilizer pellets, it is dispensable to buy dryer and cooler. However, when you start NPK fertilizer granulation with disc granulator or rotary drum pelletizer. You’d better use the dryer and cooler to remove excessive moisture from your NPK fertilizer.

Packaging equipment

Provided you want to make NPK fertilizer continuously, an automatic bagging machine is necessary. It can help you finish NPK fertilizer packaging quickly and easily, so you can deliver it to your customers in a short time.

How to prepare NPK fertilizer with NPK fertilizer blending line?

Are you finding an economical NPK fertilizer plant design? You can choose NPK fertilizer blending line. But for it, you need to use granular chemical fertilizers as materials. Then how does it work to process them into required NPK fertilizer?

Feeding various materials in proportion

If you want to produce NPK fertilizer you need, it is important to ensure the proportion of materials feeding. Static batching machine has a high degree of automation. It can help you finish quantitative feeding easily and greatly save the time and cost of NPK blending fertilizer production.

Mixing evenly

As the name suggests, mixing plays an important role in NPK fertilizer blending line. BB fertilizer mixer overcomes the mixtures chromatography and distributaries phenomena caused by different proportion of raw materials and pellets size. So it can help you mix different granular chemical fertilizers evenly and easily, then produce NPK fertilizer you need.

Packaging final NPK fertilizer

After mixing, you can pack the mixed NPK fertilizer directly and sell them to your customers.

Which NPK fertilizer making line is more suitable for you?

Do you know which NPK fertilizer manufacturing system is more suitable for you? Here, you can consider it from the following 4 items:

Material shape

When you use powder or powder + granular chemical materials, we recommend you choose NPK fertilizer granulation line. However, when it comes to granular complex fertilizer materials processing, it is advisable to setup a NPK fertilizer blending plant.


For those who have enough budget for NPK fertilizer manufacturing, our NPK fertilizer granulation system is your optimal option. Adversely, if you need a NPK fertilizer plant design for low cost production, you can choose NPK fertilizer mixing line.


These two NPK fertilizer production plans both can be used not only in small scale NPK fertilizer making, but also in large scale NPK fertilizer production. But there are also some differences between them. The largest capacity of NPK fertilizer granulation line is 30 t/h. But the large scale NPK fertilizer blending system can process 20-40 tons of NPK fertilizer per hour for you.

Area occupation

If you have a big workshop for NPK fertilizer preparation, NPK fertilizer granulation line is your best choice. In addition, for starting NPK fertilizer making in a small place, we also can offer you NPK fertilizer blending system.
